باب فِي صِفَاتِ الْجَنَّةِ وَأَهْلِهَا وَتَسْبِيحِهِمْ فِيهَا بُكْرَةً وَعَشِيًّا ‏‏

Jabir reported:

I heard Allah's Apostle (ﷺ) as saying that the inmates of Paradise would eat and drink but would neither spit, nor pass water, nor void excrement, nor suffer catarrah. It was said: Then, what would happen with food? Thereupon he said: They would belch and sweat (and it would be over with their food), and their sweat would be that of musk and they would glorify and praise Allah as easily as you breathe.
حَدَّثَنَا عُثْمَانُ بْنُ أَبِي شَيْبَةَ، وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ، - وَاللَّفْظُ لِعُثْمَانَ - قَالَ عُثْمَانُ حَدَّثَنَا وَقَالَ، إِسْحَاقُ أَخْبَرَنَا جَرِيرٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي سُفْيَانَ، عَنْ جَابِرٍ، قَالَ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ ‏"‏ إِنَّ أَهْلَ الْجَنَّةِ يَأْكُلُونَ فِيهَا وَيَشْرَبُونَ وَلاَ يَتْفُلُونَ وَلاَ يَبُولُونَ وَلاَ يَتَغَوَّطُونَ وَلاَ يَمْتَخِطُونَ ‏"‏ ‏.‏ قَالُوا فَمَا بَالُ الطَّعَامِ قَالَ ‏"‏ جُشَاءٌ وَرَشْحٌ كَرَشْحِ الْمِسْكِ يُلْهَمُونَ التَّسْبِيحَ وَالتَّحْمِيدَ كَمَا يُلْهَمُونَ النَّفَسَ ‏"‏ ‏.‏
